Warner Bros. studio canceled the Arkham Asylum series, the events of which were supposed to unfold in the new Batman universe from director Matt Reeves.
The showrunner of the project was supposed to be Antonio Campos, while the development of the tittle was from the fall of 2022. The publisher transparently hinted that the fate of Arkham Asylum may change if another showrunner is found for it. As noted in the media, it's not that WB didn't want to produce the series, management didn't like Campos' vision for the project.
Well, we wait and hope that Arkham Asylum will have a different executive.
